screenshotDo you develop audio equipment – amplifiers, preamplifiers, loudspeakers? Then you know that one of the most annoying things is the cabling of the different components: sound card, preamplifier, power amplifier, speaker and computer. There are some circuits on the internet that specializes in specific measurements. But now I found a project that created a universal measurement box for all kinds of audio measurements. Check out the project atĀ Unfortunately no PCBs are available and the microphone input is only unsymmetrical. However, the block schema gives you a good overview to build something similar. I’m already thinking about a project that combines the whole stuff on a single PCB.
